Sengcan said this quote

Pursue not the outer entanglements, Dwell not in the inner void, Be serene in the oneness of things, And dualism vanishes by itself.

~ Sengcan

When mind exists undisturbed in the Way, nothing in the world can offend, and when a thing can no longer offend it ceases to exist in the old way. When no discriminating thoughts arise, the old mind ceases to exist.

~ Sengcan

To deny the reality of things is to miss their reality; to assert the emptiness of things is to miss their reality. The more you talk and think about it, the further astray you wander from the truth. Stop talking and thinking and there is nothing you will not be able to know.

~ Sengcan

One thing, all things: move among and intermingle, without distinction. To live in this realization is to be without anxiety about non-perfection. To live in this faith is the road to non-duality, because the non-dual is one with the trusting mind.
